GE IS200STCIH6A IS200STCIH6ADD Primary Trip Terminal Board

The IS200STCIH6A IS200STCIH6ADD functions as a primary trip terminal board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200STCIH6A serves as the standard version for trip signal management. Its variant, the IS200STCIH6ADD, includes a conformal coating for enhanced circuit protection. Both boards handle primary trip functions for steam and gas turbine safety systems.

Core Technical Specifications

This board provides six trip relay channels for emergency shutdowns. You will also find screw terminal connectors for simple field wiring. The board stores minimal energy but uses capacitors for contact protection. Meanwhile, the backplane interface handles all power and data transfers.
